Abstract

Novel water softening products and methods of treating hard water are provided. The products comprise a chloride-free, organic salt and a chelating agent. The products are useful for regenerating ion exchange material in a water softening system and providing softened water containing both sodium and potassium ions, while avoiding the formation of undesirable precipitates (e.g., low Ksp byproducts).
